Abstract
Model socijalnih sila prilagođen je za korištenje s česticama u video sekvencama. Računaju se interakcijske sile, iz njih se izvlače uzorci za normalne video sekvence i uzorci za nenormalne video sekvence koristeći metode vreće riječi i algoritma K srednjih vrijednosti. Video se zatim analizira koristeći metode križne korelacije da bi se pronašli normalni, tj. nenormalni, uzorci na sličici, te se na temelju glasova te sličice označavaju kao normalne ili nenormalne. Programska implementacija je testirana, te su rezultati testiranja obrađeni i prikazani. Na temelju rezultata, donesen je zaključak o primjenjivosti ovakvog modela.
Abstract (english)
Social forces model is adapted for use with particles in video sequences. We calculate interaction forces for frames, extract samples for normal video sequences and samples for abnormal video sequences using Bag of Words method and K-means algorithm. Video is then analysed using cross correlation method to find normal and abnormal patterns in the frame, and based on votes, the frame is marked as normal or abnormal. The software implementation was tested, and test results were processed and presented. Based on those test results, a conclusion was made on the applicability of such a model.
